I'm using William Woody's cover flow implementation. When built with the iOS 3.1 SDK it works well, both on 3.1 and 4.0 devices. But when built with the 4.0 SDK it doesn't show the tiles on an iPod touch device with 4.0 (but it does in the simulator and on an iPhone device).
What might be the problem? What changed that might cause this?
The library also exhibits a very odd behavior in an 4.0 iPod touch device. If I run an app built with 3.1 (app A) and use the cover flow, and then I run an app with 4.0 (app B) and use the cover flow it shows the images from app A's cover flow in the background!
